Not really. All that gobbledygook still means maybe, maybe not. Its not definitive at all. That means you need to call/contact every time you want to book if you want to know and not have an arrive surprise. Further, its to avoid providing exact info...and when all is said and done they can point at it and say see...it was right there telling you nothing!
Yes that's an II catch-all so they are coveted if the resorts don't give them the correct information.
When resorts do have specific charges there's usually different wording that refers to that.
II may also not get told if there are facilities that are not working at the resort or if there's construction noise scheduled during your stay, so you have to check for those yourself to avoid a nasty surprise when you arrive anyway.
You only have to look at how poorly MVC updates the hub vacationclub website to see that II stand no chance of getting sensible information consistently from resorts.
